    The corollary to this mouse-hack is that you can use your mouse as a scanner and coupled with an OCR program, use it for getting scribbled notes uploaded to your computer.

    If you compare a counterfeit-coin-detecting expert with a purpose-built handheld device, the answer is pretty obvious.

    Until the day the people who print counterfeit coins buy a purpose-built handheld device, of course, and there's no expert around to reprogram the device because he jumped off a bridge after losing his job.

    Some one did something similar in the states several years ago. They made $200 bill with President Bush's portrait and bought some ice cream at dairy queen accepting the change. Don't know if they were ever found but this person was and I found several other stories while finding that link so yes people would accept them, unless your average cashier in Europe is smarter than over here. Admittedly not a difficult task. On the other side of the coin we do have a $2 bill that you often risk yourself using, one man was held handcuffed at bestbuy for two hours in front of everyone until someone from the secret service got there and explained that the $2 bill does exist.

    For all intensive purposes, "whom" is no longer a word. That begs the question, "who cares?"

    "intensive purposes" is retarded

    Perhaps the poster was going for "for all intents and purposes"?

    If so, ouch.

    We have a coin of our own that is not always accepted, whereas we readily accept US (foreign) coins.

    You don't see the irony in that?
